Abstract:
An active filter device and a circuit arrangement comprising an active filter device are disclosed. In an embodiment the active filter device includes sensor terminals for applying a sensor signal depending on a sensed noise signal, an output terminal for providing a correction signal that is suitable for reducing the noise signal, a signal source adapted for generating a correction signal and a high-pass filter coupled between the sensor terminals and the signal source, wherein the correction signal is generated with a dependence on a high-pass filtered sensor signal.
